. SPECIFICATION forming part of Letters Patent No. 420,584, dated February 4, 1890.

Application filed January 5 1888. Serial No. 259,853. (No model.) A

To all whom. it may concern:

Be it known that I, EUGENE F. TRENT, of Jersey City, in the county of Hudson and State of New Jersey, have invented a certain new .the novel features in claims.

In the accompanying drawings, Figure 1 is a vertical section of a lamp-burner embodying my improvement. Fig. 2 is a perspective view of a portion of the burner, the cone and another part being removed. Fig. 3 is a plan or top view of the base portion of the burner, showing certain wick raising mechanism. Fig. 4 is a detached view in perspective of means for operating the wick-raising mechanism. Fig. 5 is a detached view in perspective of a piece forming the top of an airchamber in the burner and constituting also a deflector. Fig. 6 is a plan or top View of an air-distributer, chimney-gallery, and cone- Fig. 7 is a bottom view of the same. Fig. 8 is a plan or top view of the cone. Fig. 9 is a detail showing certain bearings for shafts employed in the wick-raising mechanism.

Similar letters of reference designate corresponding parts in all the figures.

A designates the Wick-tubes. They are fiat and arranged side by side a short distance apart, as is usual. They extend through suitable apertures in the base a of the burner, and, I as shown, a short distance below the same. They are secured in the base-piece by solder or otherwise. Thebase-piece is screwthreaded, as usual, to facilitate its attach- T he wickraising mechanism comprises four shafts a a? a a The shafts a a are arranged in the same plane and extend parallel with each other and outside the wick-tube. Each of these shafts is provided with two star-wheels, which latter extend through suitable slots in the wick-tubes. The shafts a a rotate in unison and in opposite directions. They bear near one of their ends gear-wheels a a.

The gear-wheel a meshes with a gear-wheel a on the shaft a and the gear-wheel a meshes with a gear-wheel a on the shaft a The shafts of a are intermediate of and in a more elevated plane than the shafts a a The inner portions of these shafts extend between the wick-tubes and are journaled in bearings in a bearing-piece a secured to the wick-tubes. These shafts are separate, so that they may rotate in opposite directions. The

ends of the shafts a a and the outer ends of the shafts a 01, are journaled in bearings formedin metal bearing-pieces a (Shown more clearly in Fig. 9.) These bearing-pieces may be stamped up in a die out of sheet metal.

They each comprise a main portion 0., having ends a, bent at an angle thereto. These bent end portions are soldered or otherwise secured to the inner side of an air-distributer B. .Three holes 0. are stamped in the main portion a in suitable positions to receive the ends of the shafts a a (1. a Outs a extend from the edge of the main portion into the holes 00 and other cuts (L15 extend from the holes a for a distance and, as shown, at approximate right angles to the cuts a. This construction enables the ready insertion of the ends of the shafts, for the portions of metal between the cuts may be bent outwardly, (I

have shown one so bent,) whereupon the ends of the shafts may be inserted. If, then,'the outwardly-bent portions be bent back into their original position, the ends of the shafts will be securely retained in the bearing-holes to. It is to be understood in this connection that the shafts are placed in position after the bearing-pieces have been secured in the distributer B. The latteris secured to the base-piece a and is perforated. It may be of stituting a gear I). The gear-wheels a a The wheel 0 has Outside the mesh with the gear Z) when the wheel 0 is in proper position. The latter rests upon the top of the air-distributer B and is provided with a downwardly-extending circumferential flange b extending about the distributer and acting as a steadiment to the wheel. Extending outwardly from the flange b is a milled rim 11 This milled rim may be grasped by hand to rotate the wheel. When the latter is rotated, the gear-wheels a a are also rotated by the gear I). I

In burners of the class to which this belongs air is supplied from between the wicktubes to the inner sides of the flames and from outside the wick-tubes to the outer-sides ofthe flames. In my improvement all the air which is supplied to the inner sides of the flames and passes between the wick-tubes is received through the air-distributer B. In order to efiec't this, I form an air-chamber above the distributer B and wheel 0, into which all the air entering through the distributer B will be received. The top of this air-chamber is formed bya stamped-up piece of metal D. As shown, this piece'of metal has a flat top 0, a cylindrical portion a below the top, and a concavo-convex portion 0 below the portion 0'. In the top is formed an aperture 0 of such shape and size that the -pieceD may be passed downwardly about the wick-tubes, and the portions of metal surrounding the aperture 0 will fit snugly about the outer sides and ends of the wicktub'e's. hen the piece D is in position, its lower edge rests upon the wheel 0 outside the row of holes forming the gear 1). Extending upwardly from the top of the piece D are wings a. These wings may advantageously be made integral with the piece D and formed during the. operation of stamping up the latter. When the piece D is in position; the wings c extend vertically between adjacent ends of the wick-tubes in such manner as to form the end walls of an air-flue Df between the wick-tubes. Air entering the distributer B passes upwardly through holes in thewheel (l constituting the gear I) and the central aperture therein, thence into the air-chamber formed by the piece D, and thence is deflected by the piece D and passes upwardly through the fine D to the flames. The piece D therefore constitlites a deflector as well as the top of an airchamber. It will thus be seen that all the air entering the perforations in the distributer 0 passes substantially in a body to the inner sides of the flame. Of course an air distributer may be interposed in the flue D, if desirable.

All the air to be supplied to the outer sides of the flames enters through an airdistributer J. This air-distributer has a circular perforated portion (1. This portion is" shown as of concavo-eonve'x form. In ward of the perforated portion at is an imperforate cylindrical portion d. Tlie diam-' eter of the portion (1' is such that the latter will fit quite closely over the cylindrical portion a on the piece D. Above the cylindrical portion d is a flat top portion 01 This portion d is provided with a central aperture (1 whereby the distributer may be passed downwardly about the wick-tubes. Extending upwardly from the top portion (Z are wings d As shown, these wings extend upwardly at an inward angle. They are preferably formed integral with the distributer J during the process of forming the aperture (1 being portions of metal bent up from between cuts made in forming the said aperture. The distributer J and its appurtenances may all be stamped up in one integral piece. When the distributer J is in position on the burner, portions of the Wings 11 bear with considerable frictional resistance against the outer sides of the wick-tubes. By means of the cylindrical portion d, extending about the cylindrical portion 0', and the wings 1 bearing against the wick-tubes, the distributer D and other parts supported thereon are centered and steadied;

J designates a cone-supporter and chimney-gallery. This supporter and gallery is in turn supported upon the distributer J. It is shown as secured near its lower edge to the outer edge of the distribiiter J by bonding its lower edge portion about the edge of said distributer. It has an upwardly and inwardly extending concavo-conyex portion 6, which latter is shown as iinperforate. Abeve the portion e extends a chimney-gallery c. This cone-snppbrter and chimney-gallery may be formed in one integral piece.

J 2 designates a cone, which may be of the usual or any desired form and construction. It is provided with radially-extending ribs f, upon which a chimney may rest, so as to leave an air-space below the lower edge of the chimney. The cone is s'u ipoited upon tongues g, formed by cutting the metal forming the chimney-gallery and bending inwardly the portions of metal between the cuts; Other similar tongues g aid in securing the chimney. A screw h is einplo'ye'd to retain the chimney in position. The eerie-supporter J and cone J when the latter is in p'ositioii on the former, fOI'Iil an air-chamber, into which all the air entering through the distributer J is received, and fromwhic'hit is deflected by the cone against the outer sides of the flames. I

This burner provides for Properly distributing large quantities of at to the flames, whereby unusually heavy oilsinay be biirii'ed with perfect combustion, producihg a ver brilliant light.

In order to prevent the cone froth tiiriiing when in place on the burner, Iprovide it with a peripherical notch 9 adapted to reeei've a tongne g? on the cone-supporter J.
